Finding a Clinical Trial

Approved by the Cancer.Net Editorial Board, 10/2016

If you are interested in participating in a clinical trial, a good first step is to talk with your doctor. New clinical trials are being created constantly. There are a number of organizations that list open clinical trials. This helps people interested in joining a trial find one that may be appropriate for them. Remember to talk with your doctor for more information about any of the clinical trials you find.
